Tasty (Korean: 테이스티), stylized as TASTY, was a K-pop duo formed by Woollim Entertainment in 2012.[1] The group was composed of identical twins Daeryong and Soryong. They made their debut in August 2012 with the single album Spectrum.[2] In 2015, they left Woollim Entertainment. The name has since then changed to Hanch兄弟, and Daeryong and Soryong are promoting in China.

Prior to their debut under Woollim Entertainment, the duo were trainees under another South Korean agency, JYP Entertainment from 2006–2011. During this time, they spent time in the U.S., where they trained with choreographers that had worked with Beyoncé and Ne-Yo.[3] They also appeared as backup dancers for the singer and founder of JYP Entertainment, Park Jin-young.

The duo made the decision to leave the agency after five years in training, citing in an interview with Newsen the difficulty of seeing other trainees debut before them.[4][5]

Tasty made their debut under Woollim Entertainment on August 9, 2012, with the single "You Know Me (너 나 알아)". Their corresponding debut single album was written and composed by Rphabet and consisted of four tracks.

A year later, on August 7, 2013, Tasty released the single "MAMAMA", a fusion of swing and hip hop composed by Singaporean producer Tat Tong. The single's lyrics were written by Hoya and Dongwoo of Infinite H, who also featured in the music video. The corresponding four-track single album Spectacular featured a collaboration with rapper Hanhae from Phantom.[6]

On November 27, 2013, Tasty released the single "Day 'n Night (떠나가)". The music video was shot in Hong Kong and featured actress and model Esom as the female protagonist.

On July 15, 2015, Tasty announced via their personal Weibo account that they would be moving back to China and ceasing to promote in Korea. Woollim Entertainment claimed to be uninformed of their one-sided decision, and had recently been in discussions with the duo about their scheduled comeback. Tasty refuted these claims and expressed dissatisfaction with the company's management.[7] The duo then promoted in China under the name DLXL.
